Application of Smart Materials in Structural Elements of Pneumatic Vibroexciters

Abstract

Pneumatic vibroexciters which consist of smart materials’ structural elements and are operating under autovibration regime were designed. The chamber of vibroexciter actuator with changeable capacity for flowing pressured air made of shape memory alloy (SMA) were presented. Mechanical characteristics of such type vibroactuator were estimated: maximum deformation of structural element with SMA, possible force of martensitic transformation. The result of the research allows to design functional adaptive pneumatic vibroexciters with are suitable for the different purposes of technological processes.
